application filed April 29, 1920. Serial no. 377,508.

To all whom it may concern:

Be it known that I, EVERETT S. CAMERON, a citizen of the United States, residing at West Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Oil-Cooling Systems for Explosive-Engines; and -I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1, a schematic view of an oil-cooling system embodying my invention;

My invention relates to an improved Ollcooling system for explosive engines, the object being to provide an explosive engine, of whatever type and however used, with simple, light, durable, and efficient means for cooling the oil employed to lubricate its working parts.

With these ends in view, my invention consists in an oil-cooling system characterized by having a pressure-radiator in which the oil is cooled and from which it is forced where required to lubricate the working parts of the engine. My invention further consists in an oil-cooling systemcharacterized by a pressure radiator in which the oil is cooled and from which it is forced where required to lubricate the working parts of struction as. will be hereinafter described and pointed out in the claims.

In carrying out my'invention, as herein shown, I employ a motor-driven, high-pressure oil-pump 6 of any approved 'construction and herein shown as located at the rear end' of the lower half or oil-pan 7 of the crank-case of the engine. The main body of oil is located in this pan which constitutes the oil reservoir of the engine. The upper part of the crank-case, however constructed, is indicated by the reference numeral 8.

From the pump 6, the oil is forced under pressure througha small pipe 9 to a threeway valve 10 of any approved construction.

A connecting pipe 11 leads from'the threeway valve" 10 to a T 12 from which right and left inlet-pipes '13 and 14 lead to the opposite ends of an oil-cooling radiator supported upon the forward end of the chassis 15. at a point directly in front of the engine where the water-cooling radiator of watercooled engines is commonly located. Checkvalves 16 and 17 are located in the inletpipes 13 and 14 at their respective connections with the lower end-of the radiator, as

shown in Fig. 2.

Patented July 12, 1921.

As herein shown, the radiator consists of r a vertically arranged frame-18 resting at its lower end upon the chassis 15 and consist ing of groups of relatively small, vertically" arranged oilcooling pipes or tubes 19 open will. depend upon the size of the radiator.

and the character of the workto be performed. As herein shown, the radiator is made up of five groups of four tubes each, but obviously, this arrangement "may be varied as desired. A

' In the radiator shown, the oil entering the radiator-through'the inlet-pipes 13 and 14 will pass upward into the compartments 23 and 24in the lower chambered head 21,

.will rise through the'four tubes 19 of the outer groups of tubes into the compartments 25 and 26 of the chambered upper head 20.. and flow thence downward through the four tubes 19 of each of the intermediate groups of tubesintothe compartment 27 of the head 21. From compartment 27, the oil will flow upward through the four tubes 19 of the central group, whereby itwill be discharged into the compartment 28 of the. up

per head 20; 'Fronithe compartment 28 the oil will be led into a short pipe 29 mounting a combined oil-pressure gage and thermom eter of any approved construction, 'a-nd herein indicated by the reference numeral 30. This device serves to inform the user of the engine of the pressure under which the oil leaves the radiator and its'tempera I ture' at any given moment- From the pipe 29, an outlet-pipe 31 leads downward back of the radiator to a shut-off valve 32,thenoe through a pipe 33 to a T 34 connected byan auxiliary-pipe 35 tothe three-way valve 10 before mentioned. An oil-distributer pipe 36 leads from the T34 to the working of the cran -case and forming the oil reser- 1 volr of theengin'e, as already described. It will be understood that all. of the several pipes and tubes herein described are adapted 1n size'with relation to each other and to the capacity of the pump to: maintain the 011 under pressure at the time it leaves the radiator and. is delivered to the working parts of the'engine. I

In the use of, my improved system, the oil is forced b the circulating pump 6 forwardthrough the pipe 9b which it is delive re'd' to the inlet-pipes'13 and 14, passing thence through the check-valves 16 and 17 into the radiator through which itcirculates and in which it is cooled by the free move- I ment of air around the tubes which may or i 35 may not be exposed to the action of a fan.

,From the f radiator, the cooled oil passes through the outlet-pipe 31 to the distributerpipe 36by which the oil, still under pressure, is carried to and forced into the moving parts of the engine. In case the radiator is damaged or becomes deranged, or it is desired for any reason to cut it out of-the system, it is only necessary to operate the three-way valve 10 so as to cause the entire body of oil fed through the pipe 9 to be diverted through the plpe 35 to'the T- 34 and directly into the distributor-pipe 36.

arts of the engine from which the oil falls aek into theoil-pg'an 7 constituting the lower part To prevent vthe oil from being forced into the pipe 31, the shut-off valve 32 is closed.

It will. be seen from the foregoing that under my improved system, the oil employed for the lubrication of the engine is forced under pressure into an oil-cooling radiator from which" the oil is deliveredunder pressure to the working parts of the engine, and furthermore, that the radiator,

if deran ed, may be cut out of the system without interfering with the action of the pump in delivering oil to the working parts.

I claim: 1. An oil-cooling pressure system for explosive: engines, having an vengine, van oiltank therefor,a pressure pump, a pressure radiator to which the oil is pumped under pressure from the tank and: from which'it is delivered under'pressure, oil-distributing 7 means leading from the radiator to the working parts of the engineto which the Oll 1S sunulied under pressure, and means,

in the system forv cutting out the radiator without interfering with the pumping of the oil under pressure to the Working parts I of the engine.

2. An oil-cooling pressure system forexplosive engines, having an engine, an 01lradiator intov which the oil is pumped from the tank and from which it is delivered under pressure, oil-distributing means leading In testimony whereof, I have signed thisv specification in the presence of two subscribing witnesses.
